Two cells of emfs E₁ and E₂ and internal resistances r₁ and r₂ (E₂ E₁ . and .r₂ r₁ ) respectively, are connected in parallel as shown in figure. The equivalent emf of the combination is E _ eq . Then

Options

  1. AE ₁ E _ eq E ₂ and E _ eq is nearer E ₂
  2. BE _ eq E ₂
  3. CE _ eq E ₁
  4. DE ₁ E _ eq E ₂ and E _ eq is nearer E ₁

Correct answer

D. E ₁ E _ eq E ₂ and E _ eq is nearer E ₁

Step-by-step solution

eq = 1 r ₁ + ₂ r ₂ 1 r ₁ + 1 r ₂ = ₁ r ₂+ ₂ r ₁ r ₁+ r ₂ Between E₁ & E₂ .
